Newton's Laws
also known as the law of inertia, states that an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by unbalanced force.
What is Newton's 1st law?
this is represented by a line with a positive slope on a distance vs time graph.
What is an object moving away from a reference point?
This is a force which resist movement between two bodies of mass that are touching.
What is friction?
This is how many poles a magnet has, their names, and their relationship to one another in term of attraction and charge.
What are two poles. One north negatively charged pole which repels one south positively charged pole?
This is a property which all mater possess.
What is gravity?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Acceleration=Force/Mass, A=F/M
What is Newtons 2nd law?
This is represented by a line with a negative slope on a distance vs time graph.
What is an object moving toward a reference point?
this is the type of friction that acts upon the surface ares of objects moving through air or water. It is why parachutes work.
What is fluid friction?
This is what a magnet creates in the three diminutional space around it.
What is a magnetic field.
This increases with the amount of time gravity acts on a falling object experienced by the distance which the object falls.
what is acceleration and speed?
For every action, there is an equal and opposite reaction.
What is Newton's third law?
This is represented by a horizontal line on a distance vs time graph.
What is an object not in motion?
This is the type of friction that exist between stationary objects and the surface which they rest upon. (book sitting on the table)
What is static friction?
This is how the Earth's magnetic field protects the planet.
What is by deflection positively charged ions from the northern hemisphere and negatively charged ions from the southern hemisphere protection us from solar winds?
with an increase in mass there is an increase in this property of matter.
what is gravitational force?
This is represented by a straight line in any direction on a distance vs time graph.
what is an object with a constant speed.
The Daily Double :
The type of friction that exist between two objects that sliding against each other.
and
They type of Friction that exist between an object that is rolling across the surface on which it rests.
What is sliding friction and rolling friction?
This is what happens when two like poles of a magnet are near each other.
They will pull the other toward themselves.
two objects of the same shape but different masses will fall at this rate as compared to one another is dropped from the same height. They will hit the ground at this time with a difference in this.
what is the same rate, the same time, a difference in inertia and force due to difference in mass?
According the Newton's 2nd law it would require more of this to de-accelerate an object with greater mass. An example would be a comparison to stoping a bike to stoping a truck which are moving at the same speed and acceleration.
What is force?
This is represented by a curved line on a distance vs time graph.
What is an object which is changing speed?
This is what friction does to the motion of an object.
What is interferes with and slows down the motion of an object?
This is the direction the point on a compass needle always points.
What is the the magnetic North pole?
This is theorized to be caused by matter displacing the "fabric" of space and time. Thus larger objects of displace more space and time and possess more of this property of matter.
